摘要

The pump system has a housing, in which low pressure pumping unit is arranged with a suction supply for sucking water and a low pressure drain for hauling the sucked water. A high pressure pumping unit is arranged in the housing for producing a high pressure water steel with a low pressure supply for receiving water with lower pressure and a high pressure drain for the delivery of water under high pressure for operating high pressure cleaning nozzles. The low pressure drain of low pressure pump system is coupled with the low pressure supply of the high-pressure pump system.
